Product Introduction
Product Description
Silicon carbon alloys are widely used in the steelmaking and foundry industries as a cost-effective deoxidizer and carbon additive. Compared to traditional ferrosilicon, they help reduce alloying costs while maintaining stable silicon and carbon recovery performance.
Our silicon-carbon alloys feature low sulfur and phosphorus content, stable chemical composition, and uniform particle size, making them suitable for converter steelmaking, electric arc furnace steelmaking, and castings production.

FAQ
Q: What is the sulfur content of your company's silicon-carbon alloy?
A: Our standard sulfur content is ≤0.03%, and we can also customize lower sulfur content specifications according to customer requirements.
Q: Can silicon-carbon alloy replace ferrosilicon?
A: Yes. In many steelmaking applications, silicon-carbon alloy can partially replace ferrosilicon, reducing alloying costs while maintaining stable deoxidation performance.
Q: What particle size specifications does your company offer?
A: Common specifications include 10–50 mm, 10–100 mm, as well as custom sizes tailored to customer needs.
Q: Do you offer custom packaging?
A: Yes. We support big bags, small bags, and OEM packaging for export markets.
